DRAWING-SLATE ATTACHMENT.

SPECIFICATION forming part of Letters Patent N 0. 253,514, dated February 14, 1882, Application filed November .3, 1881. (No model.)

To all whom it may concern:

Be it known. that I, DANIEL S. OooKE, of Providence, in the State of Rhode Island, have invented a new and useful Drawing-Slate Attachment; and I do hereby declare that the following specification, taken in connection with the drawing making a part of the same, is a full, clear, and exact description.

The object of my invention is to produce aslate, eraser, and ruler combined and attached togetherin such a manner that neither can become separated from the others and lost; and it consists in the device hereinafter described.

The drawing shows my invention, in which A is the slate, B the frame, and G acombined rule and eraser. D Dare elastic or rubber bands, which attach the rule and eraser G to the slate-frame B, and are fastened by means of suitable eyes to the ends of the one and the sides of the other, or by any other desired means. In each end of the frame is a groove, E, for receivingaud retaining the ruler-and eraser when not in use.

The ruler and eraser O is made in the form of an ordinary wooden ruler, graduated at one edge upon one or both sides, as desired, while to the other edge there is attached, by inserta strip ofcharnoiseach end of the ruler and eraser G is an eye, through which passes an elasticorrubberband,

which also passes through a similar eye upon each side of the slate-frame and attaches the two together, the elasticity of the connectingbands permitting the eraser and ruler to be carried to any part of the slate-surface by the hand.

, When not in use the eraser and ruler 0 may be carried to either end of the slate and the edge thereof inserted in the groove E, as indicated by dotted lines, where it will be retained by the resistance of the bands D D until again removed by the hand.

It will now be readily seen that upon the removal of the ruler and eraserU from the groove E pencil-marks may be easily removed from or lines drawn upon any part of the slate upon either side.

Either a ruler or eraser may be attached separately in the same way, if the other is not required.

What I claim as my invention, and desire to secure by Letters Patent, is-

The slate A, with its grooved frame B, in combination with the ruler and eraser G and elastic bands D D, the whole combined, constructed, and arranged substantially as described.
